Returns a CacheableResultTransformer that is used to transform
tuples to a value(s) that can be cached.

retransformResults(List transformedResults,
String[] aliases,
ResultTransformer transformer,

Re-transforms, if necessary, a List of values previously
transformed by this (or an equivalent) CacheableResultTransformer.
|
List |
transformList(List list)
Here we have an opportunity to perform transformation on the
query result as a whole.
|
Object |
transformTuple(Object[] tuple,
String[] aliases)
Tuples are the elements making up each "row" of the query result.
|
List |
untransformToTuples(List results)
Untransforms, if necessary, a List of values previously
transformed by this (or an equivalent) CacheableResultTransformer.
